Yet, this known devices has some shortcomings, one of shortcoming is: because roller acts directly on the fiber of stocking, so can make fiber be subjected to excessive and unsuitable stretching to the driving of stocking, because fiber is elastomeric, particularly when fiber had high fineness, this device can bring the danger that reduces end product quality.In addition, it also needs to adjust exactly roller and acts on pressure on the stocking, the fineness difference of fiber, and required pressure is also different, and needs stretch in advance on stay pipe exactly stocking, makes that the time of location cost is longer.

Main purpose of the present invention is to overcome above-mentioned shortcoming.

According to the present invention, realized above-mentioned purpose by adopting a kind of like this device, in this device, each fabric that need locate is all provided: one can be around the stay pipe of longitudinal axis rotation, device that is used for making above-mentioned stay pipe motion and one or morely be used to detect one or more photoelectric tubes that are inserted in the mark of fabric fibre, fabric-supported pipe wherein is made of two coaxial elements, free end corresponding to the coaxial component of fabric foot can be connected with the corresponding driving element, and driving element can make this coaxial component and corresponding fabric portions rotate together.This device comprises also and during turning is used to pressure roller that fabric and stay pipe are suitably compressed that pressure roller can freely rotate around the axis parallel with stay pipe, and is positioned at the free-ended top of coaxial component.

Advantage of the present invention mainly is: can the most accurate and full out determine the position of the foot of any tubular fabric with respect to the toe robotic suturing device, make any other zone (heel part that for example have the stocking of heel of toe portion with respect to fabric, and the waist part of pantyhose) always is in predetermined position, can not make simultaneously fiber produce distortion, even when on corresponding stay pipe, fabric not being carried out stretching in advance and accurately, can both guarantee the best in quality of finished product; The present invention be advantageous in that: device according to the present invention is suitable for manufacturing, and this device still can be worked reliably after long-term work.

For a person skilled in the art, following about detailed description of the present invention by reading, simultaneously with reference to about indefiniteness embodiment accompanying drawing of the present invention, these and other advantage of the present invention and characteristics will be more readily apparent from, wherein:
